Science Says Your Favorite Candle Could Actually Be Giving You Cancer

According to Medical Daily, a team of researchers from BBC's “Trust Me, I'm a Doctor” teamed up with Alastair Lewis, a chemistry professor and deputy director at the UK's National Centre for Atmospheric Science, to uncover possible risks of using lemon-scented products.

Over a five-day stretch, the team sampled air from six York, England homes in search of volatile organic compounds (VOCs).

The VOC that caused the biggest stir over the course of the study was limonene, aka the chemical scent that keeps candles, sprays and household cleaners smelling lemony fresh.

With every two molecules of limonene released into the air, researchers reportedly discovered one molecule of formaldehyde formed.
